The COBB Tuning Uppipe is constructed entirely of rugged 304L stainless steel to maximize durability in the extreme environment of your Subaru’s engine bay.
Tubing is 14-gauge, 2-inch 304L mandrel bent stainless steel. These Uppipes are CNC mandrel bent, ensuring precise and consistent fitment, eliminating the need for a flex joint section which is prone to leaking.
Cast stainless steel flanges at either end of the tubing ensure zero warping and true mating surfaces to the exhaust manifold and turbocharger exhaust housing gaskets. A slight chamfer at both mating surfaces and precision fit machining for tubing make for smooth transition into and out of the up pipe.
Turbocharger studs are 4140 steel heat treated to class 10.9 with clear zinc plating. A 5mm hex is used to install.
The COBB Subaru Uppipe is made for the Subaru enthusiast looking to unlock power hidden within the vehicle's stock exhaust manifold. This beautiful Uppipe is built to last for many years by using top quality materials and outstanding craftsmanship.
